Definitions
- the present invention relates to a formwork system of the type indicated in the introduction to claim 1.
- the object of the present invention is to pro ⁇ cute a formwork system which contributes to reducing the afore-mentioned problems.
- the formwork system according to the invention is characterised in that the frame elements are designed with longitudinal grooves and/or keys at least in the sides which face towards the posts for engagement with corresponding keys or slots in the post, and in that the front side of the formwork side after arrangement in the frame element is flush with the front side of the post.
- the post is designed with the key, while the frame element is thus designed with the corresponding groove.
- One side of the groove (when it concerns a wall) constitutes a portion of the wall which bounds the concrete, so that the outside of the formwork side is
- the side of the frame element facing towards the post is designed with, a flange which extends parallel to the formwork side and which is arranged drawn in as much as the thickness of the side, or also there is designed in the post, parallel to the key or the groove, a longitudinal notch of right angled section which the formwork side rests against and which has such a breadth that the outer side of the side will be flush with the side of the post in question.
- the frame element must thereby be correspondingly narrower.
- the first-mentioned solution is preferred, owing to the fact that it is simpler to hold the formwork side in place when its dimensions are adapted to the dimensions of the frame element, so that it can be located with a force fit in the ele ⁇ ment.
- the formwork system according to the invention can be used both for boarding of walls and for boarding of roofs and pavements. In the last- mentioned instances it is preferred to use grooves and keys which have an angled cross-sectional form in order to obtain a locking of post to frame ele ⁇ ments. It can also be used for boarding of round
- Fig. 1 shows a part of an expanded perspective view of an embodiment of the formwork system according to the invention.
- Fig. 2 shows a vertical section through the formwork system.
- Fig. 3 shows a horizontal section through, the formwork system.
- Fig. 1 shows a formwork system 10 according to the invention for use in boarding of a wall.
- the formwork system 10 comprises a frame element 11, vertical posts 12, formwork sides 13, an upper sub ⁇ stantially horizontal beam 14, together with an equivalent beam (not shown) .
- a round-going groove 15 In outer sides of the frame element 11 there is designed a round-going groove 15, that is to say that the groove 15 is designed for all sides of the element. Parallel to one wall of this groove there is arranged a flange 16 on the inner side of the faces which face towards the posts 12. The distance of the flange from the edge of the element 11 corre ⁇ sponds to the thickness of the formwork side 13, so that when the formwork side is arranged in the frame element 11, it rests on the flange 16, while its outer side is flush with the edge of the frame ele ⁇ ment as shown in Fig. 3.
- the frame element is besides provided with cross beams or struts 17, which act bracingly and which therefore are used especially when the frame elements have larger dimensions.
- the post 12 is designed on each of the two sides which face towards the frame elements 11 with a longitudinal key 18. These keys fit in the grooves 15 in the frame elements 11.
- the keys are somewhat shorter than the post itself, in that they are cut off at the ends. There will thereby be formed grooves in the ends of the post, either in that this is hollow, or in that in addition to the keys 18 being shorter than the post itself there is cut out a groove in the end faces of the post.
- the grooves in the ends of the post are equivalent to the grooves in the frame elements 11, and correspond to a key on a face of the beam 14.
- In the post 12 there are designed besides holes 19. The object of these holes is to guide spacing pieces through them for use in double boarding. Thereby it is not necessary in such cases to bore through the formwork side itself.
- the mode of operation in using the formwork system according to the invention in the casting of a wall is as follows: On a base there is arranged a beam 14 with the desired direction and of a desired length with the key upwards. On the beam 14 there is arranged a frame element 11 with the groove 15 in engagement with the key on the beam 14. Thereafter there is arranged a post 12 with the groove in the end face in engagement with the key on the beam and with the key 18 on the one side face in engagement with the groove 15 in the frame element 11. There ⁇ after there is arranged another frame element 11 on the opposite side of the post 12, with its groove in engagement with the key 18 on the post 12. In each frame element there is arranged a formwork side 13 with a force fit and resting against the flange 16. The post 12 and a frame element 11 on each side are connected to each other with the help of locking means, usually a wedge lock 21 (Fig. 3) . The locking means also cause the formwork wide to remain sitting better in position.
- locking means usually a wedge lock 21 (Fig. 3)
- DMPI If is is desirable to have a higher boarding than the height of a formwork side or a frame element, one can arrange a beam 14, which has keys both on the under side and on the top side up on the erected boarding, and thereafter begin "anew" with the mounting of frame elements and posts. It is also possible to use posts which are equivalent to the height of several frame elements and continue with several frame elements directly on top of each other. The subsequent frame elements must thereby have keys on the under face for engagement with the groove in the upper face on the frame element below. According to the invention there is produced a simple and practical formwork system where the form- work sides, posts and edges of the frame element to ⁇ gether form the surface which faces towards the con ⁇ crete.
- the individual components are easily handle- able and make possible the erection of formwork without it being necessary to use cranes and with- out it being necessary for nailing, at any rate not in an especially extensive degree.
- the invention makes possible a significant saving of time relative to conventional formwork in smaller operations.
